Product features
Compatible with multiple sampling methods: the module can be connected to reed sampling, reluctance sampling, Hall sampling, and non-magnetic sampling base meters for precise measurement;
Remote real-time meter reading and control: It is possible to remotely read meters and control valves in real-time through the centralized collector;
Timed upload function: defaults to uploading every 6 hours;
Trigger real-time upload: Data can be uploaded in real time by triggering the magnetic switch;
Sampling fault detection function: When the sampling sensor fails, the meter uploads fault information. Valve control: The opening and closing of the water meter valve can be controlled remotely or by handheld devices;
Electromechanical synchronization: can perform both non-magnetic sampling and optoelectronic sampling.
Attack valve closing function: It has the function of preventing external electrical and magnetic attacks. When the sampling is attacked by external electrical and magnetic attacks, the meter can automatically close the valve;
Valve fault detection function: detects whether the valve is open and closed properly, and uploads valve status information; Valve washing function: The valve is opened and closed regularly to prevent rust.
